"oa/ZZ whom it may concern: v'Be it known that 1, THOMAS GEORGE HAR-OLD, of Brooklyn, in the county of Kings and State of New York, haveinvented, made, andapplied to use an. Improvement in Mosaic or ToyBlocks; and I do hereby declare -thejfol- 5 is a perspective 'view ofsaid mosaic blocks with the-saine surfaces as in'Fig. l, but thin anddat, instead of cubical. Fig. 6 is a perspective View of a block, asdescribed in Fi g. 5.

Blocks of a flat and of acubical. form have heretofore been made, `andthe. Surfaces of those bloekshav'e been painted, and blocks or fiatpieces have been made Of a triangular form for toys.

The nature of 'my said invention consists in a series of squareorcubical blocks that are painted or.colored diagonally, either in two` orfour colors on the' square surfaces of such blocks, thereby a series oftriangular gures lare producedv that can be placed together in suchamanner as to make a great varietyvof mosaic gures or patterns, eitherfor designing or forchildrens .toys'or building-blocks, thus y for thepurposes specified.

combining' inthe said blocks eubioal and tri-v angular shapes andvarious colors, so as to' increase the interest in to children and togive Opportunity for greater exercise of theirfae. ulties inthe-.placement of such blocks.

The character of my invention will be fully understood On'reference tothe drawings, Figs,

'2 and, in which the blocks are shown sepan rately. The surfaces of saidblocks are formed in triangular Spaces by ;diagonals from either the twoor the four corners of the square. surfaces upon these blocks. Thepainting or coli oring upon the surfaces of these blocks is to l beeffected by stencil-plates, or by painting them in straight linesdiagonally to the Square ofthe 'blocks' when severa-l are placedtogether, as illustrated in Fig.'l. These blocks should be in sets, andplaced in suitable boxes adapted to their reception'. j The sunface ofthe Wood vmay remain with out being colored or painted,and form one ofthe colors on such surface.

What I olaim,.and desire to secure by Letters Patent, ,is-

A series of sqnareor cubical blocks Whose surfaces are colored intriangular forms, as and In Witnesswhereof I hereunto set mysignaturethis 26th day of May, 1864.
